No idea on these cars situations today but #94 CSX2558, #95 CSX2557 & #96 CSX2513 are all Team Shelby America cars.
#60 is CSX2290 of Randy Hilton, what's the other #?
Could be the '64 Bridgehampton 500 as at least 4 of these cars raced there together, see this link...http://www.racingsportscars.com/phot...964-09-20.html
